Find the date that is a number of days, weeks, months or years before or after any date. Nothing leaves your browser.
Days and weeks are added as exact calendar days. Months and years keep the same day of the month, or move to the last day of a shorter month. Dates use the Gregorian calendar.
Pick the start date, choose Add, enter the number of days and press Calculate. The result shows the new date and its weekday.
If the target month is shorter, the date is moved to the last day of that month. January 31 plus one month is February 28 (or 29 in a leap year).
Yes. Days are calendar days. Weekends and public holidays are not skipped.
No. Everything is calculated in your browser and nothing is sent anywhere.
